Nvidia DGX Spark encrypted firmware slows inference speed to 35% on Linux
Comments on “Nvidia DGX Spark encrypted firmware slows inference speed to 35% on Linux”
3 judges. Scored by all three judges. Only the day’s top stories get the claim check. How far stories are checked
Testers found that the Nvidia RTX Spark laptop running Linux stays stuck at about 780 MHz GPU clock when plugged in, compared with roughly 2.2 GHz on Windows, cutting GPT-OSS-120B throughput to around 14 tokens per second.
Why it ranked
No. 106 of 139 with a score of 0.56. The panel rated it highest on new information (0.90) and technical depth (0.79), lowest on audience breadth (0.47). Overclaim counted against it (0.50). The judges disagreed most on overclaim (spread 0.57), so the story is marked contested. Placed No. 106, No. 129 by score alone: the sixth Hardware & devices story of the day (−0.060). The placement terms move stories; they are not part of the score.
- AI judgeJudge 2claude-haiku-5-5
- Detailed hands-on report of Linux performance problems on an Nvidia RTX Spark laptop with concrete benchmarks, useful to AI/hardware builders, though narrow in audience and based on one user's testing.
- AI judgeJudge 3gpt-5.6-luna
- Concrete Linux-versus-Windows benchmarks, clock measurements, firmware diagnosis, and practical WSL guidance make this valuable to AI developers. The headline’s 35% figure conflicts with the body’s roughly 21% result, and injected ads slightly reduce confidence.
